At a glance

Customer sentiment is overwhelmingly positive: buyers repeatedly praise Gatorback/SharpTruck mud flaps as premium, heavy‑duty, great-looking, vehicle-specific products that provide excellent protection, with standout customer service and fast shipping. The main negatives are high price, occasionally challenging/long installations (especially rears/dually), and periodic hardware/instructions/packaging issues or minor fitment quirks on certain trims/oversized tires.

What Customers Liked

  • Thick/heavy rubber, substantial weight, rugged/OTR-grade feel; holds up for years (5–10+ years reported), flexible in cold/snow, doesn’t “sail” at highway speed; strong brackets add stability.
  • Look “sharp,” “classy,” and OEM-like; logo/plate options (Ford/Chevy/Ram/AT4X/Z71/flags, etc.) get many compliments and add ‘pop’.
  • Many report perfect fit/‘like a glove,’ good tire coverage, options for offsets/oversized tires (e.g., offset versions preventing rubbing), adjustable positioning via slotted holes.
  • Significantly reduces mud/road salt/slush on running boards/steps and sides; helps prevent rock chips and protects trailers/RVs/boats; improves cleanliness on gravel/dirt roads and in winter conditions.
  • Often installs using factory holes and avoids drilling into metal body; videos and written instructions frequently cited as helpful; many install without removing wheels (fronts especially).
  • Consistently praised for responsive support, warranty replacements for tears/rips, quick resolution of shipping damage/wrong parts/missing items, and proactive communication/updates.
  • Fast delivery (often 2–5 days), accurate orders/fitment tools, good packaging noted by many; easy ordering and exchanges/returns.
  • Removable lower section on some models appreciated for added clearance during off-roading, then quick reinstall.

Things to Consider

  • Frequently described as expensive/‘hard pill to swallow’ (some citing $600–$1000+), though many still say it’s worth it.
  • Rears and dually setups often challenging/time-consuming; some recommend removing rear wheels, using a right-angle drill, clamps, or a helper; alignment can take time.
  • Some find written directions vague/confusing; hardware not clearly labeled (washers/spacers), left/right not distinguished, videos not always model-specific; “no-drill” marketing criticized when drilling in liners/plastic is still required.
  • Occasional missing screws/washers/clips/parts; mixed metric/SAE hardware complaints; plastic fasteners/clips stripping or pulling out; desire for stainless/black hardware and better washer/spacer labeling.
  • Some reports of rubbing with oversized tires/turning lock; minor misalignment of holes/templates; driver/passenger side fit differences; not perfect fit for some newer model years or with wheel-well liners/fender flares/steps.
  • Several note rear support brackets feel ‘necessary’ but are not always included; frustration at needing to add brackets separately or not being told upfront.
  • A few cases of brackets coming loose in transit causing scratches; damaged outer boxes; occasional wrong color/plate shipped.
  • Silver fasteners/washer heads stand out; some plates/finishes streak or rust (rare report of rust forming on logo); desire for thicker metal in certain kits.
  • Some note flaps hang low for off-road use; risk of tearing in deep snow, tall grass, or trail obstacles (though removability helps on some models).

The mud flaps are good but I did not use the self taping screws. The self taping screws strip to easily

These flaps are simply the best available for your pickup. This is my fourth truck I have installed them on over the years and when the time comes they will go in my fifth.

For starters they obviously have a high end look. They clearly are not your generic auto zone Walmart straight off the shelf flaps. They are quite heavy. This ensures that they stay in place and do not blow back and become ineffective at speed. The stainless panels not only add a custom touch but they also ensure that as time goes in the flaps do not curl at the bottom.
These flaps wear like iron, and look superb year after year.

Mine are the 26inch length. I ordered the 23 inch and found they were too short for my preference. A simple phone call to Sharp Truck and we quickly remedied my situation.
Love Sharp Truck and I love my Gator Back Flaps.   These photos show the front 26” flaps and the rear 26” flaps with the custom mounting brackets.
I DRILLED ZERO HOLES IN MY TRUCK TO INSTALL THESE FLAPS. ALL ATTACHMENTS WITH THE CUSTOM BRACKETS ALLOW FOR THE USE OF FACTORY INSTALLED FASTENERS.
The front flaps are the basic front flap cut and I was able to securely mount them entirely with factory screws.

Truck Hardware Gatorback "High Country" Logo Dually Mud Flaps - Set

For Chevy Silverado owners who want to protect their truck while adding a touch of distinction, the Truck Hardware Gatorback "High Country" Logo Dually Mud Flaps are the ideal solution. Specifically designed for 2015-2019 Chevy Silverado 3500 HD (Dually Rear Wheel) models, these mud flaps offer unmatched protection against road debris while enhancing your vehicle's appearance with the sophisticated High Country logo. Combining quality craftsmanship and rugged performance, these mud flaps are a perfect upgrade for any proud Chevy truck owner.

Constructed from heavy-duty virgin rubber, the Gatorback High Country Dually Mud Flaps are designed to endure the toughest conditions while providing flexibility and durability. Each rear flap weighs 10 pounds, ensuring that they stay firmly in place without 'sailing' or shifting, even at high speeds. These mud flaps offer extensive tire coverage—5 inches for the front and 9.5 inches for the rear—providing maximum protection against rocks, mud, and road grime that can damage your truck's finish. The officially licensed High Country logo is die-stamped into a stainless steel plate, featuring a hand-applied vinyl overlay, delivering a professional and premium look.

The High Country logo, set against a sleek stainless steel plate, provides a distinctive and refined aesthetic that complements your truck's bold design. These mud flaps are engineered not just for their protective qualities but also to elevate the visual appeal of your truck, offering a rugged yet polished look that makes a statement.

Installation

Front Flap Installation: The front mud flaps fasten directly to the lip of the wheel well using self-tapping screws, and existing factory fasteners can be used if available. The installation process is straightforward, requiring only basic tools. Be sure to allow at least 1/2" of clearance between the tire and the wheel well to accommodate the flap's thickness. The front flaps install flush to the wheel well, allowing seamless integration with accessories like step bars, power boards, or side steps.

Rear Flap Installation: The rear mud flaps come with custom-fit Gatorback dually mounting brackets, which are essential for ensuring a secure and stable fit. These galvanized steel brackets provide a solid mounting point, keeping the heavy-duty flaps securely in place even under challenging conditions. The rear brackets utilize existing factory holes, eliminating the need for drilling into the truck body, though drilling through the mud flaps themselves is required. This installation method ensures the mud flaps are tightly secured, reducing the risk of flapping into the tires. The rear plates, which measure 17 1/4" x 5", add a bold, distinctive visual element to your truck.

  • Officially Licensed Chevrolet High Country Logos: Stainless steel plates with hand-applied vinyl overlays ensure a sleek, high-quality appearance.
